There could be a detective - like character in 'the locked door short story'. If the locked door is part of a mystery, perhaps a detective is called in to solve the case. There might also be an old caretaker of the building where the locked door is located. The caretaker might have some knowledge about the door but is reluctant to share it at first.

I don't know since I haven't read the novel. But they could be two young lovers, or perhaps it involves a more complex set of characters like a group of friends where a love story develops among them.
